Description

Anordning for elektrisk forbindelse mellom to skinnesystemer som krysser hinannen i innbyrdes avstand. Device for electrical connection between two rail systems that cross each other at a distance from each other.

Foreliggende oppfinnelse vedrorer en anordning for elektrisk forbindelse mellom to skinnesystemer som krysser hinannen i innbyrdes avstand* Oppfinnelsen er særlig egnet ved skinnesystemer som er bygget opp av skinner med rektangulært tverrsnitt, hvor de til de forskjellige systemer horende skinner er vendt med smalsidene mot hinannen. Forbindelser av denne art forekommer eksempelvis i lavspenningss ti Uverk, hvor samleskinnene er forbundet med skinnene i en såkalt skinnebro som utgjor en forbindelse mellom to parallelt anordnede saraleskinnesystemer. The present invention relates to a device for electrical connection between two rail systems that cross each other at a distance from each other* The invention is particularly suitable for rail systems that are made up of rails with a rectangular cross-section, where the rails belonging to the different systems are turned with their narrow sides towards each other. Connections of this kind occur, for example, in low-voltage substations, where the busbars are connected to the rails in a so-called rail bridge that forms a connection between two parallel-arranged busbar systems.

Hittil har sådanne forbindelser som regel vært utfort således at endene av skinnene i skinnebroen er boyd til å ligge i samme plan som samleskinnene, hvoretter samleskinnene og skinnene i broen kobles sammen ved hjelp av forbindelsesskinner med samme tverrsnitt ©om de dvrige i anordningen inngående skinner. På hvert forbindelsessted blir så skinnone vanligvis presset sammen ved hjelp av gjennomgående bolter for oppnåsIse av det nodvendige kontakt trykk. Å fremstille en sådan forbindelse er relativt tidskre-vende, særlig i de tilfelle hvor hvert skinnesystem er bygget opp av flere parallelle skinner. Hver skinne må nemlig boyes, bores og tilpasses individuelt, hvilket ofte forutsetter adgang til verk-tøymaskiner. En eventuell utvidelse av skinnene i et allerede foreliggende stillverk kan derfor nedfore store vanskeligheter og om-kostninger. Up until now, such connections have usually been made so that the ends of the rails in the rail bridge are bound to lie in the same plane as the busbars, after which the busbars and the rails in the bridge are connected together by means of connecting rails with the same cross-section as the other rails included in the device. At each connection point, the skin is usually pressed together by means of through-bolts to achieve the necessary contact pressure. Producing such a connection is relatively time-consuming, particularly in cases where each rail system is made up of several parallel rails. Each rail has to be bent, drilled and adapted individually, which often requires access to machine tools. A possible extension of the rails in an already existing structure can therefore entail major difficulties and costs.

En forbindelse utfdrt i henhold til oppfinnelsen ved skinner av den type som det her dreier seg om, er ikke beheftet mad de ovenfor nevnte ulemper. Det nye ved anordningen er at de hinannen kryssende skinnesystemer er forbundet med hinannen ved hjelp av et antall langstrakte kobleelementer som trykkes mot de to skinnesystemer ved hjelp av omkring kobleelementenes endepartier anordnede klemorganer, idet kobleelementenes kontaktflater mot de forskjellige skinnesystemer ligger i forskjellige innbyrdes kryssende plan. Ved en sådan forbindelse behoves der ikke foretas noen spesi-ell bearbeidelse av de i skinnesysternene inngående skinner, bort-sett fra eventuell behandling av kontaktflatene for å hindre oksy-dasjon. For skinnesystomene kobles sammen, hvilket kan utfores med de vanligst forekommende monteringsverktoy, behoves der således bare fremstilles kobleelementer og klemorganer. Da disse elemen-ter imidlertid ikke behover tilpasses for en bestemt skinnedimen-sjon eller for et bestemt antall parallelle skinner i de to kryssende systemer, kan de fremstilles industrielt i forholdsvis stor målestokk. Oppfinnelsen medforer på denne måte at jaonteringstiden og dermed omkostningene for forbindelsen kan minskes betydelig. A connection made in accordance with the invention with rails of the type in question here is not affected by the above-mentioned disadvantages. The new thing about the device is that the mutually crossing rail systems are connected to each other by means of a number of elongated coupling elements which are pressed against the two rail systems by means of clamping means arranged around the end parts of the coupling elements, the contact surfaces of the coupling elements against the different rail systems being in different intersecting planes. With such a connection, there is no need to carry out any special processing of the rails included in the rail cylinders, apart from possible treatment of the contact surfaces to prevent oxidation. For the rail systems to be connected together, which can be done with the most commonly found assembly tools, it is therefore only necessary to manufacture connecting elements and clamping elements. However, since these elements are not adapted to needs for a specific rail dimension or for a specific number of parallel rails in the two crossing systems, they can be produced industrially on a relatively large scale. In this way, the invention means that the connection time and thus the costs for the connection can be significantly reduced.

Kobleelementet kan hensiktsmessig utfores av skinneformet materiale, f.eks. kobberskinner med rektangulært eller kvadratisk tverrsnittt, som skjæres av i passende lengder. Som oftest vil de to kryssende skinnesystemer være anordnet i hovedsaken vinkelrett til hinannen, i hvilket tilfelle kobleelementet av skinne« materiale ikke behover å vris for at dets kontaktflater skal oppnå riktig stilling i forhold til de kryssende skinner, av hvilken grunn fremstillingen av elementet blir særlig enkel. The connecting element can suitably be made of rail-shaped material, e.g. copper rails with a rectangular or square cross-section, which are cut to suitable lengths. Most often, the two crossing rail systems will be arranged mainly perpendicular to each other, in which case the connecting element made of rail material does not need to be twisted in order for its contact surfaces to achieve the correct position in relation to the crossing rails, for which reason the manufacture of the element becomes particularly simple.

I henhold til en videre utvikling av oppfinnelsen er kobleelementet utformet som en nod to parallelle ben forspent bSylie sous hensiktsmessig asordfeøs fer delvis å oKfislutte en skinns i det ene system. Denne utforclso har blajat asrøet éssm fmåél at alle \ kobleeleannter forst kan anbringes i riktig stilling på skinnene, I hvoretter forbinde lsesstedene trykkes samiaen ved hjelp av kle mor ga-nene. Montasjen blir på den måte meget enksl og kan lett utfores ;av en eneste person. According to a further development of the invention, the coupling element is designed as a nod two parallel legs pre-tensioned bSylie sous expedient asordfeös fer to partially oKfisclose a skins in the one system. This research has led to the fact that all the connecting elements can first be placed in the correct position on the rails, after which the connection points are pressed together with the help of the clamps. In that way, assembly is very simple and can easily be carried out by a single person.

To eksempler på ifolge- oppfinnelsen utforte forbindelser er vist på tegningen, på hvilken fig 1, 2 og 3 viser en forbindelse mellom to på hinannen kryssende skinner sett i tre vinkelrett på hinannen stående projeksjoner, mens fig 4, 5 og 6 på samme måte ; viser en forbindelse mellom to kryssende skinnesystemer, som hvert består av fire parallelle skinner. Two examples of connections made according to the invention are shown in the drawing, in which figs 1, 2 and 3 show a connection between two mutually crossing rails seen in three projections standing perpendicular to each other, while figs 4, 5 and 6 in the same way; shows a connection between two crossing rail systems, each consisting of four parallel rails.

På fig 1, 2 og 3 er vist to skinner 1 og 2 som krysser hinannen i rett vinkel og ligger i en viss avstand fra hinannen. Skinnene har rektangulært tverrsnitt og er vendt med smalsidene mot hinannen. Skinnen 1 kan eksempelvis være en saiuleskinne i et lav-spenningsstillverk og skinnen 2 en såkalt skinnebro son er bestemt til, eventuelt over en samleskinnebryter, å forbinde samleskinnen Figures 1, 2 and 3 show two rails 1 and 2 which cross each other at right angles and are at a certain distance from each other. The rails have a rectangular cross-section and are turned with the narrow sides towards each other. Rail 1 can, for example, be a saiule rail in a low-voltage switchgear and rail 2 a so-called rail bridge designed to, possibly via a busbar switch, connect the busbar

og 2 er innbyrdes forbundet ved hjelp av tre boyleforméde kobleelementer 3> hvis ben ligger inntil skinnen 2 på den ene henholdsvis annen side av denne, mens de samme ben delvis omslutter skinnen 1. Forholdet mellom overflatene av de på tegningen viste skinner and 2 are mutually connected by means of three boyle-shaped connecting elements 3> whose legs lie next to the rail 2 on one or the other side of this, while the same legs partially enclose the rail 1. The relationship between the surfaces of the rails shown in the drawing

og kobleelementer er således valgt at der bor anvendes tre kobleelementer for forbindelsen mellom de to skinner. To av disse ele-menter er anordnet på skinnens 1 ene side og det tredje på skinnens annen side. Omkring koblecleiarntcnes endcpartier er der anordnet skruekleracicr, ned hvilke kobleoleirantene presses mot skinnene for tilveiebringelse av god elektrisk kontakt. Disse kler.sr består av parvis like, i hovedsaken rektangulære plater 4 henholdsvis 5 soro 1 er skrudd cacaen ved hjelp av et antall gjennomgående bolter 6 som på tegningen bare er skjematisk antydet ved boltenes senterlinjer. and coupling elements have been chosen so that three coupling elements should be used for the connection between the two rails. Two of these elements are arranged on one side of the rail 1 and the third on the other side of the rail. Around the end sections of the coupling elements, there are arranged screw clamps, down which the coupling elements are pressed against the rails to provide good electrical contact. These kler.sr consist of pairs of identical, essentially rectangular plates 4 and 5, respectively, and 1 are screwed together using a number of through-bolts 6, which are only schematically indicated in the drawing by the center lines of the bolts.

Fig kt 5 og 6 vieer hvorledes et skinnasysteia beståen-i ds av fire parallelle skin&or 1 er forbundet med et kryssende skisi-i iiesystem bestl',en&3 av fire parallelle skinner 2, ved hjelp av tolv kobleeleæanter 3. ISåde skinnene og kobleelemente.Ee haz sasuae di-mensjoner som de som er vist på de foregående figuren, cg forbin-deisen er utfort på analog måte. Kobleelementene trykkes mot skinnene 1 henholddsvis 2 ved hjelp av de av plater 7 henholdsvis 8 og bolter 6 bestående klemmer. Som folge av forbindelsesstedenes forskjellige storrelse er der anvendt klemmer av forskjellige dimen-sjoner ved de viste utforelser. Fordvrig fremgår det at man med en eneste type av kobleelementer kan tilveiebringe forbindelser mellom kryssende skinnesystemer med vidt adskilte totalarealer. Ved at skinnene ikke behover å boyes og bores, kan monteringsarbei-det forenkles betydelig. Med ifdlge oppfinnelsen utforte skinne-forbindelser kan man dessuten på enkel måte ved behov utvide skin-nesystemenes arealer. Figs 5 and 6 show how a rail system consisting of four parallel rails 1 is connected to a crossing system consisting of four parallel rails 2, by means of twelve coupling elements 3. Such are the rails and coupling element. haz sasuae dimensions as those shown in the preceding figures, cg the connecting ice is carried out in an analogous manner. The connecting elements are pressed against the rails 1 and 2 respectively by means of the clamps consisting of plates 7 and 8 respectively and bolts 6. As a result of the different sizes of the connection points, clamps of different dimensions are used in the embodiments shown. Otherwise, it appears that a single type of connecting element can be used to provide connections between crossing rail systems with widely separated total areas. As the rails do not need to be bent and drilled, the assembly work can be considerably simplified. With rail connections made according to the invention, the area of the rail systems can also be easily expanded if necessary.
